Chipped Bone in Ankle

I am a 35 year old male with regular exercise, mostly running.
On New Year’s day, I turned my ankle playing basketball.
Xray shows chipped bone below ankle.
I was put in cast for 3 weeks.
Started biking in gym last week (finally).
Running still causes discomfort and a tiny bit of pain.
Ankle still feels weak.
Some say bone injuries take 2-3 months to get to 90%.
But then this is a minor bone chip rather than fracture.
Any ideas when I can get back on the treadmill and finally outdoor (pavement) running?
Thanks for your advice.
